the chamber or column. is connected by a pipe 13 with the intake manifold 3, so that the gas from the generator commingles jwith theair and is supplied to the combustion valve lfl which is located in the pipe 13, and is preferably providedwith a connection 15 which enables the throttle valve to be controlled by the operator. f
